A new sea pool and saunas have opened at Helsinki’s Market Square, allowing visitors to do laps, relax and even take a dip in the ocean year-round.

The Allas Sea Pool “revitalises Helsinki’s traditions as a spa city and brings the citizens of Helsinki an oasis of good life in the heart of the city”, according to the website. It’s located in the city’s South Harbour at Market Square – or Kauppatori – which is Helsinki’s most famous market and a touristy square where traditional goods, handicrafts and souvenirs are sold.

The site has one large freshwater pool and one freshwater pool for children, both of which are filled with water heated to 27 degrees Celsius. There is also one sea water pool, filled with purified sea water. The temperature in that pool actually changes with the sea, meaning that anyone interested in an authentic ice swimming experience in the Finnish winter can try it out at Allas. For those who will need to warm up after a dip in ocean temperatures, there’s also a women’s sauna, men’s sauna and a shared sauna that can also be rented out. The temperature in the sauna will hit about 80 degrees Celsius.

The Allas area will be able to fit about 3500 people at a time and the pool is hoping to get about 300,000 visitors per year beginning in 2018. In addition to the pool, there are restaurants, shops, conferences rooms and more. There are also plans for concerts and other events year round, such as DJ nights. The pools and saunas are open every day of the week and tickets are €9 for adults.
